Oil seal sealed lazy and oil spill countermeasures
1.Master and identify the basic knowledge of shoddy products, buy high quality, standard oil seal.
2.Installation, if the shaft diameter of the outer surface roughness or rust, rust, burr and other defects, to use fine sand or linoleum polished smooth; in the oil seal or shaft diameter corresponding to the location of cleaning oil or grease. Oil seal outer ring coated with sealant, with a hard paper on the shaft of the keyway parts wrapped up to avoid scratching the oil seal lip, with a special tool to seal the oil into the inside, do not hard hit hard red. To prevent the oil seal deformation or squeeze the spring and failure; if there are lip flanging, spring off and oil seal skew must be removed when the reload. It should be noted that: when the shaft diameter is not worn and the oil seal spring is sufficient, do not tighten the inner spring.
3.Application of agricultural machinery on the oil seal general working conditions are poor, the ambient temperature difference, dust and more frequent vibration of the machine to make mechanical conditions continue to change, to check, maintenance and maintenance.
4.Such as shaft diameter and bearing wear serious; oil seal rubber aging or spring failure, etc., should be promptly repaired and replace the corresponding parts.
5.On the abnormal heat of the parts or assembly should be promptly troubleshooting; to avoid mechanical speeding, overload operation, to prevent the oil seal lip temperature rise, rubber aging, early wear and tear mouth.
6.Always check the oil level, if the oil impurities too much, there are alloy powder, metal iron scraps to completely replace the new oil. Change the brand and quality of oil to meet the requirements of the season.
7.Temporarily indispensable oil seal, should be properly kept to prevent stains, dust or sun exposure.
8.When the shaft diameter wear into a "V" -shaped groove, so that the new oil seal lip and shaft contact pressure drop can not play the role of sealing oil. Can choose AR-5 two-component adhesive adhesive, both simple and reliable and wear-resistant. Can also be used to make up the method of oil seal shift. The specific method is: the general rubber oil seal, can be added to the oil seal forward or backward shift, staggered on the shaft diameter wear groove. For the limit of the skeleton oil seal, you can turn the front frame shell L 5 ~ 2mm, plus pad shift. If the oil seal outer cylinder and bearing seat larvae have been loose, the size can be used to restore plastic governance.
